What problem does it solve? Code reviews often miss real defects or drown in nitpicks and unverified suspicions. This Skill enforces an adversarial, evidence-first review process that confirms every finding against the actual code before reporting it, producing an accurate merge decision. ## Core Features & Use Cases - Adversarial verification: Starts from the hypothesis that the change contains a serious defect, then tries to falsify each suspected issue before reporting it. - Contract-first analysis: Establishes requirements, backward compatibility, and scope before judging the implementation, so intended behavior changes are not mislabeled as regressions. - Structured verdict reporting: Leads with confirmed findings ranked by severity, each with file/line location, violated contract, failure path, impact, evidence, and a minimal fix direction. - Use Case: Ask it to review a pull request before merging; it inspects the full diff, traces failure paths, runs safe read-only checks, and returns either confirmed findings or an explicit clean pass. ## Quick Start Ask the agent to review the current branch diff or a specific pull request and report confirmed findings with severity and merge readiness.
